Default New Bonneville. Maintenance Questions?????

Ok so I am new to the Bonneville and I have some maintenance questions. I have a 2002 SSEI with 55000 miles on it.

1. Do I need to get the supercharger oil changed? I saw something about it in the owners manual. Also how much does this cost to have done?

2. Do the tranny fluid and radiator fluids need changed?? I have heard bad things about tranny fluid flushes. Also is the radiator fluid easy to change?? Anyone have directions on how to do it.

3. I just ordered new Taylor Spiro Plug wires. Should I upgrade to better plugs like Platnium or something?? Are the plug hard to change??

I think that covers most of my questions. Am I forgeting any other things that need to be done?? I put new metallic pads and new rotors on the car. I also put in a K&N filter and I am going to sythentic oil on the next change. Just want to make sure I am not forgetting anything. Thanks.

According to Eaton and GM, the SC is sealed for life. So change the oil once every two years. I do it once a year. Instructions are in Techinfo.


2. Do the tranny fluid and radiator fluids need changed?? I have heard bad things about tranny fluid flushes. Also is the radiator fluid easy to change?? Anyone have directions on how to do it.

We've seen no evidence here that flushing is bad, unless possibly on a VERY high mileage unit that'* never had a flush before. I flush once a year. I suggest you start with a pan drop and change the filter. That'll get 1/3 of the fluid.


3. I just ordered new Taylor Spiro Plug wires. Should I upgrade to better plugs like Platnium or something?? Are the plug hard to change??

Ditch the Taylor wires. We've had alot of bad stories with them, myself included. I had 2 bad sets out of the box, and another failed prematurely. Run Belden Premiums. If this doesn't convince you, use an Ohmmeter to check the resistance of the wires BEFORE you install them, and again after you route them from the coils to the plugs before final connections. Treat them with kid gloves, and report your resistances back here. Treat them very delicately if you insist on using them. Also add wire loom (protective cover) everywhere they touch anything.


Consider changing your front O2 sensor for performance and efficiency. They're getting tired at 50k or so. Ignore the rear O2 sensor, it'* purely for emmissions.

Any AC Delco or NGK plugs other than Platinum. Platinum and Boost don't mix. Irridium are fine. Autolite'* are also a favorite here. Change the plugs if you don't know how long they've been in there.

Radiator fluid? I'd have that completely flushed if you have the $$ to do it. Otherwise Just drain the radiator for now (petcock under the radiator on the driver'* side, access through a small hole on my 93, not sure about your year). Replace with a 50/50 of dex-cool, not the green stuff.

O2 sensor is sticking right out the top of your rear exhaust manifold. Looks like a spark plug, and you'll see it when you do your plugs. I do it with a crescent wrench, but you're a little more restricted for space. It might make it easier to pull it before doing the plugs, then put it back last.

I would go ahead and change the plugs. I changed mine at 61,000 miles last year and there wasn't much left of the tip. Double ditto on ditching the Taylors.

I just ordered the Belden wires and some AC Delco Iridium plugs. Now should I gap them to 0.6 like stock or should they be something else??

I am also going to hold off on the tranny for flush for right now. I am going to drain and fill the radiator.

Thanks for the help.

If your running the stock pulley you should stick with the stock gap. as your boost level increaces (smaller pulley) you can tighten gap.
